![]() In addition to MySQL 5.7.17, you will need to download the MySQL InnoDB cluster package for your system from, which will contain: Group Replication provides synchronous replication for InnoDB and built-in automatic failover, while the Router lets applications connect to an appropriate member of the cluster with no changes to their code, other than an update to the MySQL connection parameters.ĭownloading and Installing Required Packages In this tutorial, we will use the new MySQL Shell to create 3 sandbox instances, create a 3 member Group Replication cluster with them and setup MySQL Router as a proxy to hide the multiple MySQL instances behind a single TCP port. The MySQL team at Oracle has now released a preview of a solution that aims to make it easy to combine multiple instances of MySQL together in order to provide redundancy for High Availability of the MySQL databases used by your applications. So many people end up procrastinating setting up HA until disaster strikes and downtime happens. From understanding concepts and technologies, to the tooling, specific commands and files to execute and edit, there’s a lot of things you need to know even when planning a test deployment (the Quick Start Guide for Group Replication should give you an idea). Nuff said.Traditionally, setting up high availability (HA) in MySQL has been a challenging task, especially for people without advanced knowledge of MySQL. Adobe had to mature Muse to the point where it was useful for simple websites, not just web sites that are simply gimmicky.īut Adobe Muse has somewhat restored my faith in the fact that one day, maybe Sir Tim Berners-Lee's original vision of simplicity is restored. Truth be told it was rediscovered because it has been out for a while but there were two bridges I had to cross: 1) I had to come to terms with Adobe's subscription model which I hate, but needs is as needs must, and 2) I had to have sufficient time to learn Adobe Muse. Well, just when I thought I would be with Sandvox until HTML freezes over, I discovered Adobe Muse. True, there are some things that Sandvox cannot do (tables being the main one), and there really isn't a user manual for it (but there's lots of help files). True, that day included learning Sandvox and diddling with a little bit of CSS and HTML - it seems that a web site just has to be a cacophony of languages. ![]() Not only did I create the first version of this website in just a day but it has a built in blog function. And it damn near overkilled us.Ĭlearly Joomla! and Drupal were not the ways to go.Īnd then I discovered Sandvox. Furthermore, the CSS required to make even a simple web page work was overkill. Nor can you use a single instance of Joomla! to create multiple web sites. There was no apparent way to handle a development and live version of the web site without complex procedures. And this is just to create a minimalist web site!Īnd you cannot even just move the web site from one server to another - you have to hassle with both the data files and the SQL database and perform a multi-step ritual to move the web site around. But dudes, really! To use it you have to learn Joomla! (no surprise there), but then you also have to know CSS, HTML, PHP, JavaScript, Apache, some GoDaddy rituals, and, oh, yeah, mySQL. I'm sure it has its followers, its devotees, its gurus, and its cognoscenti. Massively overdesigned for the task at hand. Complex web sites need complex design tools, but.whoof. ![]() ![]() And we concluded that it was massively overcomplicated, arcane, and fit only for those in the priesthood who wanted to devote their lives to it. My colleague and I, with a total of over 80 years of systems programming experience between us, had a close look at Drupal. I've just spent several weeks and several hundred dollars of consulting fees, flogging a dead horse in order to create a simple, elegantly designed web site.įirst we tried Drupal. I just happened to find it on the Internet in a place that suggested it was not copyrighted and it seemed to convey the appropriate sentiment to what might be wrong with the world of technology. I have absolutely no idea what the back story is for this image. Blogging a Dead Horse Andy Johnson-Laird Sunday December 9, 2013 ![]()
